To all whom it may concern:

Be it known that l, JEAN ll. OLINGER,

dial to be used. with ordinary clocks, since the winding-hole or holes-W1 1 be uncovered of lriiluurnlzee, in the county of lvlilwaukee 1 whenever they are opposite the spaces be and State of ll'iscousin, have invented a. Goographu it index for Clocks, of which the following is a s1 ecilication.

In my toriner Patent No. 935,806 issued "October 5, 1909, I described a means of showing upon an ordinary cloclodial the hours for various principal points or coun tries all around the earth; said means COL sisting in fixing to the hour-hand arbor of a clock, or otherwise mounting so that it will rotate with the hour-hand and concentrically with the clock dial, a, disk having" a ring divided into 534 radial sectors alternately black and white which reproscnt the different cities, countries or points of the earths surface. l have found by experience that said dial as disclosed in iny aforesaid patent presented certain disadvantages which.it is the object of the present invention to avoid by means of certain improvements whici will hereinafter appear. I

Standing clocks are frequently wound through an aperture in the dial thereof, and

when said dial is covered by an annular disk such as that described and claimed in my former patent it has the disadvantage of covering the winding-hole so that a spe cial winding-device is necessary in order to wind the clock; and this makes it inappli cable or diilicultly applicable to ordinary clocks. Another disadvantage which said annular disk presents lies in the fact that the aforesai sector-shaped divisions of the disk so run together at their edges that it is not easy to tell at aglance which (lurk segments belong with which light ones, and to find any desired segment, and the hour indicated byit, rcquiressrmie search, be cause the edges of the segment run together.

In my present improved index I provide a dial which is in the form of a star ,hnv

ing 12 rays, each of which carries a hand time i gain the advantage of enabling ssid' tween the rays, at which time a hey rm" supplied. l'iioreover in my present U tion the meaning and method of readin the dial is obvious to alniost any one at a ghu'icc and requires no instructions or set of rcctions, which in public cloc a ry lnlpOlttlhll element, as the public will not stop to study out a device which recpiires time and pains. In my present i'orin (it. index I may reovcr dispense with the hour-hand entirely, by coloring one of the 12 points, being the point corresponding" to the place where he user is located, a special color or tint, or otherwise distinguishing it from the rest, whereby it takes the place oi an houi hond,

My invention comprises, more preci%ly stated, the construction which will be here inattter more particularly described and is set forth in my claims, reference being had to the accompanying drawing, Figure 1 of which shows a tocewiew at the index, and Figs. 2 and 3 respect-ivcly,'sidc and end views of an attachmentthereior.

7 The index has a central aperture sot the diameter of the hour-hand arbor or sleeve and. adapted to slide over the same and to be fixed thereto in any desired manner, example that shown in my aforesaid patent. immediately concentric with the aperture 8 is preferably placed a. irtographic polar projection a of the earth as shown, divided by meridians, which Wlll in this case be dial, at-l5 degrees interval, and these may be properly designated in the numbered circ e b. This map and circle are, however, not essential to the invention. The outer periphery is formed by the twelve equidistant star-points j, which are longitudinally divided into light and dark divisions as shown,

and terminated by the hand or pointer On the dark and light spaces of each point. are placed the names of places at opposite meridians of the eartln'and these may be marked with their corresponding longitudes. example, the uppermost starpoint of the drawing is designated London in the light, space and Fiji Islands in the dark space; the former being nun'r bored 0, which is the meridian of London, and the latterlde', which is the meridian. of

lldiji' Islands. On the pointer-s in are placed the respective time nuinber '3', said numbers dealing the difference e l loom beingd: iqnzitee 1S Lin ad or colored is indieaiecl by the shaded lines. So tinted or colored, said star-point "would serve the purpose of an hour-hand for a person located on or near 25 llie meridian of Milwaukee or ihzii of Cal- L the index is carried onlhe watch of ferson who is traveling, or upon a. clock 'eh is being moved from one point to uni inslead of liming or coloring one of "e points, a linied translucent overlay 0r '3 may be used, as for example a piece eellnloid or isinglnss, monnled eonenlly Willi the hour arbor by means hole nnd having tabs 17 on its edges pied to engage temporarily ever the of any one of the Sli1T-POIIiiS said nay be freely moved from one sluro the other by simply raising the end songs ling the labs (Z from one starnd placing the strip over another one. e l have hereinahove shown the most form of my invention, 1 Wish it ood that not all of the features are l. thereto or necessarily made in the not form shown, but various changes and diiioatii'ins in i'he constructions as herein wn may he made without departing from 'n soil-it of my invention, and 1 wish it l 7 00d therefore (hat the latter is not ise limited than by the. scope of my airing thus described my invention, nil l Cliillil 21 v new and desire to secure by Pnienl is:
